Smartphones are no longer just callers, becoming full-fledged control centers of the digital world. Xiaomi Redmi Note 9 Pro is a prime example of such a versatile gadget that can not only consume content, but also distribute it. In situations where fixed Internet is not available or is unstable, the Wi-Fi distribution function becomes critical for work, study or communication.
Activating the MIUI modem on the Redmi Note 9 Pro may seem like a trivial task, but the system offers many subtle tweaks: optimize power consumption, improve connection security, and even hide the network from prying eyes. Understanding these nuances will help you use your smartphone as efficiently as possible, turning it into a reliable router anywhere in the world.
In this article, we will take a look at all the steps of setting up, from basic enablement to advanced security settings, and learn how to change the network name, set a strong password, and choose the optimal frequency range for stable operation of connected devices.
Basic activation of the access point through settings
The easiest and most obvious way to start a web feed is in the system settings menu, so you first need to unlock your Redmi Note 9 Pro screen and find the Settings icon, which usually looks like a gear, which is preferable if you are setting up the hotspot for the first time or want to change the basic network settings.
In the menu that opens, you should scroll down to the "Additional Features" section. This is where tools that are not directly related to calls or multimedia hide. Find the Wi-Fi Access Point and click on it. If you use the newer version of MIUI, this item may be simply called "Access Point" or located in the "Connect and Sharing" section.
When you go to the menu, you'll see a switch at the top of the screen, put it in the active position, and the smartphone will start broadcasting the Wi-Fi signal. By default, the network will be called the model of your phone, for example, the Redmi Note 9 Pro, and access to it will be protected by a password, which can also be changed in the same window.
- 📱 Open “Settings” and go to the “Additional Features” section».
- 📡 Select the "Wi-Fi Access Point" option and activate the switch.
- 🔒 Check the network name and password, changing them to more convenient if necessary.
- 👀 Make sure that the mobile internet is on or the handset won’t work.
Importantly, once the access point is activated, the status bar will have an icon that looks like an antenna or two chains, which signals that the modem is running and ready to connect other gadgets. If the icon does not appear, check if there is an In-Airline mode that blocks all wireless connections.
Quick access through the notification curtain
For power users who need instant internet access, there is a faster way to activate. The Xiaomi Redmi Note 9 Pro, like most Android devices, has a quick control panel. To get there, you swipe from the top edge of the screen down. Some firmware versions require you to do this twice to open the full menu.
Among the many icons, find a symbol signed as "Access Point." It can look like radio waves or a key. If you don't see this icon on the first page, try swiping left or right -- often hidden in additional pages of the control panel.
This is ideal for situations where you need to quickly share the Internet with a friend or connect a laptop, but it is worth remembering that you can not change the security settings through the curtain or see who is connected to your network.
⚠️ Note: When activating the access point through the curtain, make sure that you have mobile traffic enabled. 4G/LTE switched off, other devices will be able to connect to Wi-Fi, but will not get access to the Internet.
Sometimes users are faced with a situation where the button in the curtain is gray and not pressed.This may mean that the function is limited to the operator or currently activated power saving mode blocking background activity.

Add the Access Point widget to your desktop for even faster inclusion without opening the curtain.
Security settings and password change
Wireless network security is not just a formality, it's a necessity, especially when you're in public.The standard password generated by the system is often too difficult to manually type on devices without a keyboard, so it's wise to change it to memorable but resistant to hacking.
To change the settings, go to the access point menu and select "Setting up the access point." Here you will see a field «SSID», You can rename the Redmi Note. 9 Pro in anything, for example, «Free_Wifi_Lure» joke «My_Secure_Net» The key is not to use special characters that may not be supported by older devices.
The Password field below is recommended to use a combination of letters of different register and numbers at least 8 characters long. The system also offers to choose the type of encryption. The Redmi Note 9 Pro is relevant to the WPA2 PSK and WPA3 PSK standards. The latter provides a higher level of protection, but some older laptops or tablets may not see it.
| Parameter | Recommended value | Safety impact |
|---|---|---|
| Type of encryption | WPA2/WPA3 Personal | High (protection against data interception) |
| Password length | Minimum 10 characters | Critical (complicates selection) |
| SSID cover-up | Off (default) | Medium (hiding the network from the list, but not protecting traffic) |
| Device limit | 1-3 devices | High (access control) |
The Hide Device feature deserves special attention. If you activate this switch, your network will no longer appear in the list of available Wi-Fi on other gadgets. To connect, you will have to manually enter the network name (SSID) on the client device, which creates an additional barrier for casual users, although it is not an absolute protection against hackers.
☑️ Network security check
Frequency range choice: 2.4 GHz vs. 5 GHz
One of the key features of the Xiaomi Redmi Note 9 Pro is support for dual-band Wi-Fi. In the settings of the access point, you can choose the broadcast frequency: 2.4 GHz or 5 GHz. This parameter directly affects the data rate and signal coverage radius.
The 2.4 GHz band is more common and compatible, and it provides better signal penetration through walls and obstacles, making it ideal for spreading the Internet in large rooms or outdoors, but this range is often overloaded with neighborhood routers, microwaves and Bluetooth devices, which can slow down speeds.
The 5GHz range offers significantly faster data rates and less interference, and is a great choice for watching 4K video, playing online games, or downloading large files on a connected laptop, but it has a significant drawback: the range is much smaller, and the signal is worse through concrete walls.
Settings -> Wi-Fi Access Point -> Access Point settings -> Frequency RangeIf you don't know which option to choose, leave the default value. The smartphone will analyze the surrounding air environment and choose the optimal channel. In most cases, the automatic mode works quite efficiently for everyday tasks.

The system allows you to set a tight limit on the number of users you connect to. Usually the default is a limit of 10 devices, but to save battery and traffic, it is wiser to reduce this number to 2-3. This will prevent a situation where neighbors or passers-by accidentally connect to your network if they somehow learn the password.
Blacklist is also available, and if you notice an unknown device, you can block it with a single click, and once it's locked, it won't be able to connect to the network even if it knows the right password until you remove the restriction, and it's a powerful tool to protect against uninvited guests.
- 👁️ Regularly check the list of connected devices in the access point menu.
- 🚫 Use the lock function for unknowns MAC-address.
- 📉 Set a connection limit (e.g., 2 devices) to save charge.
- 📊 Keep track of the amount of traffic transmitted so as not to exhaust the operator’s packet.
⚠️ Note: Some mobile operators may block or limit speed when giving out internet (TTL-If the speed on the connected laptop is low, although everything is flying on the phone, it is possible that the operator applies restrictions.
Optimizing energy consumption and solving problems
Modem mode is one of the most energy-intensive processes in the smartphone. Xiaomi Redmi Note 9 Pro is equipped with a battery capacity of 5020 mAh, which allows you to comfortably distribute the Internet for several hours, but under intense load the phone can heat up. High temperature negatively affects charging speed and battery durability.
To minimize the risks, try not to cover the phone during the handout and remove a dense case if you feel a strong heat. It is also useful to reduce the brightness of the screen or turn off the display altogether, since it consumes a significant part of the energy. In the battery settings, you can turn off background applications that are not needed when the modem is running.
If the access point is not turned on or permanently shut down, try to restart the smartphone. Often the problem is resetting the network settings to the factory (this will not delete your photos or contacts, but will reset Wi-Fi and Bluetooth passwords -> The phone -> Reset the settings -> Reset your Wi-Fi, mobile network and Bluetooth settings.
